Cannes N. "Coir a citi ze1 1= .of the United States, residing at tiom This invention relates to automatic head lamp controls the objectgin :VIEW being to.

Brmkxuan in. the county of Lassen and- State of alifornia, have invented newhnd c lmproveiiients in. Dirigible Headlights; of which the following isa specific! provide sim 1e means applicable to anyinotorvehic e either at the time of-inanufacture or subsequent thereto,- whereby one "or more lamp' s'areso controlled'zbythe steep v in' mechanism hereinafter described, that said lamp or lamps are automatically turned to theright or to the. left in accordance with thedirection or angles assumedvby the steering wheels of the machine. f a 7.

One of theprincipal objects of: the present invention is to provide simple means whereby the lamp turning mechanism may be readily adapted to illfierent makes of machines and whereby also the lamp or lamps may be caused to turn at equal angles with the steering wheels or atrzgreater or "less angles. 1 By reason of the arrangement here-,

The

bracket is connected to the base or supportportion of which isreceived 1n a notch 21 in a down-turned flan'ge22 (if the guide bracket B, said spring tongue serving to hold the guidebracket Bin a normally. central position while allowing the same to yield in order that the guide bracketmay be turned on its pivotal connection with the member 12. u

a The secondary motion transmitting member or rodis formed at one extremity with an eye or hole 23'to receive a combined pivot and set screw 24 which extends therethrough andthrough a radial opening'25 in a clamp 26 which surrounds a lampturning arm 27 connected with the lamp post, whereby the point' of pivotal connection between the secondary motion transmitting member or rod and the lamp turning arm 27 may be mcreasedor diminished for the purpose of' giving greater or less throw to said lamp turning arm and correspondingly regulating the amplitude of movement of the lamp and the post by which the lamp is carried. The

lamp' 28 is mounted u on the upper end of a post 29, the latter cing supported andjournaledin ball bearings 30 in a bracket 31 fastened to the front endof the body of, the

vehicle as for example,xthe radiator or the sub-frame which supports the radiator. The bracket 31 carries an arcuate stop plate formed with a 'longitudinalslot 33uwhirh rcceives adjustable. stops 35 serving to limit the movement of an arm 34 extending from the lamp post; The-stops 35 limit the turn ing movement of the lamp in oth directions irrespective of the angle to which thesteering wheels are turne connection between the member 12 and the ide bracket 3 allows for this difierenre in he movement of the steering wheels and the lamp" and thereby prevents injnry to the lamp turning mechanism in case thestee'ri'n'g wheels are turned to a greatcranglc than the "lamp. 36 designatesa supporting or ,rail forthe secondary motion transmitting member.

In Figs. '8 and- 9, l have illustrated the mechanism as a )plied to a'connectiug rodwhich is located in advance of the front axle, the construction "being identical with that hercinabm'e described with the exception that the lam turning arm 27 is reversed-or lit to extend-inthe opposite direction. In

provided on its mner-facewith a stud or The spring tongue either a single lam or a lurality of lamps 37 at one'end, the extremities of which are connected by a clhmping bolt 38 enabling the arm "to be firmly clamped around the lower end of the lamp post 29. In order to prevent slippage the band or collar 37 is projection 39 which 'is adii'pted to enter either one of a pair of diametrically opposite notches in the post 29.

In Fig. 10, the principle of the invention is shown applied to a vehicle employing a pair of head lamps 41 arranged at opposite sides of the radiator or bodyeof the machine,

the lamp turning arms 27' ing coupled to gether by a connecting rod 42 so as to cause both of the lamps 41 to turn simultaneously and equally in the same direction. Underthe arrangement shown in .Fig. '10, the secondary motion transmitting member 43 is attached to the -connecting rod 42 and,

passes-through the guide bracket B carried by the primary mption transmittin memher A In the same relation as heremabove described. S

- From the foregoing description taken in connection with the accompanying drawings it "will now be understood that as the-connecting rod' 5 is moved in a sulista itially longiti'ulinal direction, a corresponding movement is imparted to the primary motiontransmitting member Aand thereby to the base or supporting member 1.2 and the guide bracket B. A correspondin movement is also .ii'i'iparted to the secomlhry mo- "movement of the. lamp is regulated by varytiontransmittingmember which in turn acts ingth'e distance between the vertical axis ofthe lamp post and the point of connection between the lamp turning arm and the secondary motion transmitting memberj In view of the fact that-the primary motion transmitting member is adapted to rock on a. horizontal axis, all relative up .and down movement lwtwecn the body. and front axle of the machlne is: compensated for.
